History: Discovered by Ramsay and Travers in 1898 in the residue left after evaporating liquid air components.

Xenon is a member of the so call noble or inert gases.

Xenon is present in the Martian atmosphere to the extent of 0.08 ppm. the element is found in the gasses evolved from certain mineral springs and is commercially obtained by extraction from liquid air.

Uses: The gas is used in making eletron tubes, stroboscopic lamps, bactericidal lamps, and lamps used to excite ruby lasers for generating coherent light. Xenon is used in nuclear energy field in bubble chambers, probes, and other applications where a high molecular weights is of value.The element is available in sealed glass containers of gas at standeard pressure. Xenon is not toxic, but its compounds are highly toxic because of their strong oxidizing characteristics.
